I repeat, please acquaint yourself with the language before making pronouncements about it, so that you will not spread misinformation. C++ compilers use a variety of means to decide when to generate "elaborations" of virtual functions. In general, even if this happens in multiple compilation units, linker directives are used to indicate that all of the instantiations must be identical and they are then merged into a single copy. There is only one virtual table for a class, merged in the same way if needed, so it "looks the same" by definition. I have no idea what constructors have to do with any of this, since constructors are never virtual. You just seem to be confused. > Some C++ style guides suggest not to use virtual inlines because of it. Some C++ style guides are desperately out of date, and others have been written by people with the same lack of knowledge of C++ that you show. Some descriptions of Ada report that it's a language designed by a committee, is bloated, was forced upon people by the military, and is generally unsuitable for any purpose.
